ORGAN STOP-ACTION.

SPECIFICATION forming part of Letters Patent No. 443,426, dated December 23, 1890.

Application filed September 2,2, 1890l Serial No. 365,702. (No model.)

To all whom, t may concern: ing the respective mutes, as will be herein- 5o Be it known that I, NEWELL M. BOYNTON, after explained. a citizen of the United States, residing at E indicates the octave-coupler, consisting Brattleborough, in the county of Windham of a series of rocker-levers c, of well-known Y 5 and State of Vermont, have invented a new form, (only one of Which is here shown), fuland useful Improvement in 'Organ-Actions, crumed upon the hinged board or supporter, 55 of which the following, together with the act0 be brought into action in the usual mancompanying drawings, is a specification sufiiner by elevation of the forward edge of said ciently full, clear, and exact to enable persons supporter.

The connecting-link D and D indicate the mutes hinged to the I is made of wire, with one of its ends passed 'cell-board for stopping off the different sets through the end of the tilting lever H and 45 of reeds or sounding devices in the usual manbent as a hook, while its other end is bent in ner. The back mute D has a projecting pin the form of a ring and embraces the crank f, 9; or stud cl', and the front mute has a strap d, said ring being lined with a loop of felt or and the operating mechanisms are connected clot-h, as at i. The felt t' is held in position with said stud and strap for opening and'closby the ring being closed down upon the extended ends of the felt, (see Figs. 2 and 3, forming a simple and etlicient joint that works easily and without noise.

J indicates a cranked-wire lever f ulcrumed, as at j, ou the brace er back-board K, which is recessed and grooved for the reception thereof. Said lever has at its lower end a lateral bend or offset J disposed in position for contact with the Wheel h of the tilting lever, while the upper arm of said lever J has a lateral bend or offset J2, that passes through or engages wit-h the pull-bar or stop M. A series of these swinging levers, corresponding Vin number with the tilting levers ll, and stop-pulls are employed. The 4pullbars are of usual form and are arranged in the name-board I1 in well-known ina-nner. When the stop-rod M is drawn out, the lever J is caused to swing, and its laterally-offset lower end J moves backward in a positive line, passing' into contact with the wheel 7L, thereby effecting the depression of the rear end and elevation of the front end of the tilting lever Il by the wheel h rolling beneath the end J the action being smooth and easily effected by reason of the free rotation of said wheel. The front end of the tilting lever Il being thus elevated draws up the link orconnecting-rod I, vin the ease of the first lever ll raising the mute D', and in case of the second lever Il causing partial rotation of the shaft F by lifting its crank f, so that the cranked front end f of said shaft will raise the front mute D, and in the caseof the third lever Il rocking the shaft F, so that its laterally-offset curved end I?? will press upward theboard E and put the octave-coupler into position for engagement with the buttons b of the keys and the flanges c of the tracker-pins C.

In the present instance I have shown only three stops, that number being sufficient to illustrate the construction of the mechanism 5 but it will be understood that in practice any desired numberof stops maybe used in a single organ, the individua-l stop mechanisms consisting of the pull-bars M, sitting-lever J, tilting lever ll, with wheel 7i., and connections from said levers being as herein illustrated and described, the back inntes D having connections direct from the ends of the tilting lever Il, while the front mutes D and the ocrave-couplerll are provided with transverselydisposed rocker-shafts, as F F, with cranked endsf to receive the connecting-links at the front ends of the tilting levers.

P indicates a horizontal shaft, expressionroll, or rocker-bar extending longitudinally of the action and disposed adjacent to the front ends of the tilting' levers ll. Said shaft is provided with pins or fingers n, which project backward u nder the ends of the levers Il, and by means of which all of the series of levers Il can be simultaneously elevated by a partial rotation of the shaft I. This shaft l? constitutes the full organ or knee stop, and is journaled or pivoted at its ends to rocki freely, and is connected with the usual. kneeoperating device in any suitable or convenient manner to be actuated when desired.

I am aware that an expression roll or shaft having iin gers has heretofore been employed for the grand-organ stop, and therefore do not claim such device otherwise than in the combination herein shown. Neither do I claim, broadly, the use of wire swing-levers fulcrumed on the brace in connection with stop-pulls, as such levers have heretofore been employed, but, so far as I ain aware, in different construction and combination from that herein set forth.

I claim as my invention, to be herein secured by Letters Patentl. The combination, substantially as described, of the tilting lever Il, fulerumed at Il and provided with a -wheel h, pivoted in its bifureated rear end, the stop-pull M, the swinging lever' J, formed, as shown, with the central hingin'g part'j, whereby it is fuleru med on the brace K, the laterally-offset lower end J', disposed for engaging said wheel h below the fulcrun1,tl1e laterally-offset top end J?, engaging with the pull above the fulcrum, the connecting-link I, and thc mute D', for the purposes set forth.

i. The combination, substantially as described, of the tilting lever H, fuleruined at Il and having the wheel 7L mounted on its rear end, the transversely-disposed rockershaft F, having the laterally-offset lifter end f and the crank-arm f, the link I, connecting said crank-arm with the forward end of said tilting lever,the swing-lever J ,fulcrumed on the brace l and having an offset lower end that engages the wheel 72., and the pullbar M, connected with the top arm of said lever, for the purposes set forth.

3. The transversely-disposed shaft F, having the crank j" and laterally-offset curved end F2, in combination with the octave-coupler E, the link I, the tilting lever H, the swinglever J, and the pull-bar M, all disposed for operation substantially as shown and dcseribed.

i. The combination, substantially as described, of the stop-pulls M, the swing-levers J, fulcrumed on the back piece lf and having the offset ends J2 and J, the tilting levers Il, having the wheel h pivoted in the bifureated rear end thereof, the connecting-links I, earrying the felt-supporting ring z, the cranked rock-shafts F F, the mutes D D,octave-eeup ler E, and expression-roll P, having fingers n., that extend beneath the ends of said tilting levers, all disposed as showmand for the purposes set forth.
